Abstract: COMPLETE SPECIFICATION FOR DUAL FUNCTION - CERAMIC LINED - VERTICAL SHAFT GUNITE SPRAY MACHINE - WITH MULTIPLE SPRAY NOZZLES This invention of robot type has an electric driven rotation pack internally fitted to rotate the two centre tubes, thus allowing the 90 degree diversion flutes to rotate 360 degrees while expelling the shotcrete in spray from from the nozzles. The robot is hoisted up & down by a winch mounted gantry to allow the robot to lower into vertical tunnels. With the experience gained in operating & improving the spray robots function ability since the concept was imported into Australia, I have used my knowledge & experience to invent an alternative spray robot that has the following advantages: * Double the capacity of fibrecrete that can be expelled by introducing a twin nozzle system that will function with two spray nozzles & two pumps, rather than the single pump & single nozzle systems currently being used. This will maximize production, & support the shafts before extensive damage occurs after the shafts have been developed or bored. " Improve the monitoring & functions of the robot with improved CCTV systems (cameras on board). This system uses 6 cameras housed inside a specially designed camera housing which injects air in front of each camera lens to deter dust & foreign materials from spoiling the view. * Using a Triangular shaped body instead of round or square the overall girth of the robot is minimized to enabling the robot for use in smaller diameter shafts. " The Triangular shaped body also allows flexibility to the guides (outriggers) to be adjusted for multiple sized shafts * Introduce variable voltage lighting functions on the robot to improve vision & glare issues experienced on other model types " Introduce a laser type depth measuring system to offer a high degree of accuracy of robot location inside the shaft in favour of the encoder type systems currently used on other models * With the triangular Prism shaped cover on the top of the robot, this Improves the overall protection of the robot from falling objects or failed ground support. The fallen object is deviated away from the robot, instead of falling onto a flat surface as seen on other models " The robot has been designed with a full lining of ceramic where fibrecrete passes through from the rubber hose to the entry point at nozzle, opposed to sectional ceramic components used on other models whereas tempered steel is also used to minimise wear by the highly abrasive fibrecrete * The design comprises of a twin cable suspension method (two winch ropes to suspend robot from surface) to allow two conveying hoses to be separated from each other & coupled to the twin winch ropes at intervals to minimize man handling when recovering robot to the surface These Drawings & text remain the property of Kylie Braes & Shane Hollis.
